The significance and importance of India’s Northeast region is a key component of its eastward interaction. Given its geographic closeness and sociocultural ties to India’s eastern neighbours, the Northeast region is significant for India’s eastward engagement. In addition to strengthening sociocultural engagements, it offers plenty of room and opportunity to advance economic integration and connectivity. Given this potential, Northeast India’s involvement and responsibility became stressed as a key element of the Look East Policy. The relevance and importance of Northeast India in India’s eastward engagement have been emphasised more since 2014, when the “Look East” policy gave way to the “Act East” policy. Notwithstanding the enormous potential it has, the Northeast region has numerous issues and difficulties that have prevented it from realising its full potential, including underdevelopment,political upredictability, and inadequate governance. Additionally, the region is under-represented in the creation and implementation of India’s “neighbourhood policy.” Ensuring the Northeast region’s effective involvement and integration in the “Act East” Policy is necessary to turn the region’s potential into reality.
